Take this fun online X-Rite color challenge to test your color acuity.  I'll tell you now that I scored a 14; a lower number being better.  It does take a few minutes to complete the challenge, but I think you will find it interesting.  Shoot me an email with a screenshot of your results and I'll post a small spreadsheet of all our results when I've collected enough of them.  I'll leave out any personal data or names, only collecting the results from x number of people.

There was some discussion at our December 5 meeting about the upcoming assignment “complementary colors” for January. Steve Schuenke mentioned a web-based tool called Color Scheme Designer, an interactive color wheel. Below is the link to the web site along with a tutorial on complementary colors where it is used on Phlearn. Enjoy.
